Study on the Wear Resistance of Al₂O₃ Particles Reinforced Epoxy Resin Composite Coating

Abstract:

The study examined the wear resistance of Al₂O₃/epoxy resin composite coating including the composite curing agents and its ratio,fillers volume fraction and its particle size.The results show that, firstly, when the low molecular polyamide and phenolic amine composite curing agent were added into the epoxy resin system within a proper ratio ,it can improve the coating wear resistance property, especially the quality ratio is 1:1. Secondly, when the fillers particle size is fixed, its volume fraction ranges from 0 to 36.8%, when the volume fraction is 23.4%, the wear resistance property is better. Thirdly, when the fillers volume fraction is fixed, its particle size ranges from 28μm to 106μm, when the size within the range of 58-75μm, it can significantly improve the wear resistance ,the best wear resistance is about 3 or 5 times of the basal material Q235,having a higher cost performance. Besides, the coating resistance mechanism was investigated.
